SARAH M. HOYT, OF CHICAGO, ILLINOIS.

PAVING-BLOCK.

SPECIFICATION forming part of Letters Patent N0. 394,770, dated December 18, 1888.

Application filed August 16, 1887. Serial No. 247,077. (No model.)

To all whom it may concern.'

Be it known that I, SARAH M. IIOYT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paving-Blocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Hy invention relates to paving-blocks, and its object is to form a solid curved base for an upper surface composed of cement or other suitable material, which upper part may be a separate molded block with a crowned upper surface tapering slightly toward the ends of the block, as described in my patent, No. 364,928, of J une 14,1887, or may be composed of cement, &c., poured upon or otherwise placed upon the base and having a level upper surface.

My invention is illustrated in the accompanying drawings, in which- Figure l is a perspective view of the base, and Fig. 2 asimilar view with the base and top formation united.

As shown in Fig. l, A is the base, in the form of an arch, made of baked clay, cement, iron, wood, or any other suitable material and in any suitable manner, and provided with perfor-ations b. In Fig. 2 the block is shown complete, C being the top surface, solidly connected with the base A.

One method of making my improvement is as follows: Suppose a walk six feet wide is desired. I first form in a mold a base of clay constituting' a half, quarter, or other part of a circle of the length mentioned, and, say, twelve inches wide, provide the base with perforations, and then bake the same. I then fill up the mold with any suitable cement to form the top surface, which may be simply cement or other composition in imitation of stone.

.made level.

The material poured in runs through or into the perforations in the base, and when the material is set the two parts are united solidly together, one forming a solid base, the other a top finish and attractive appearance for a walk; but I do not confine myself to this method, as the arch may be laid with cement in or on a mold resting upon the ground, and when set the mold may be withdrawn and the upper surface filled in, or other similar methods may be employed, without departing from my invention, which consists in the product and not in the mode of its production nor in the manner of its application.

This product may be made, as above described, the whole desired width of a sidewalk, or it maybe made in sections and of any size. It may be made on the sidewalk, or the blocks may be made at distant points, in which latter case the base described will answer the excellent purpose of strengthening the upper surface and obviate danger of breaking in transportation of the same, and, as already intimated, the top surface may be arched to correspond to the base, may taper from end to end, as in my previous patent, or may be Such upper surface, also, may be provided while in a plastic state with any ornamental design or configuration.

Having thus described m f invention what I b 7 claim is- A paving-block composed of two sections in combination, a lower arched section constituting the base and provided with perforations, and an upper solid section united to said base, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
